JOSEPH MORSOHHAUSER, OF POUGHKEEPSIE, NEW YORK.

BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 254,835, dated March14, 1882.

Application filed January 20, 1882. (Model) To all whom it may concern:

Beitknown thatI, J OSEPH Monsonnaussn, of Poughlreepsie, in the countyof Dutchess and State of New York, have invented certain Improvements inBottle-Stoppers,ot'which the following is a specification.

My invention relates to that class of bottleclosing devices wherein aswinging bail or stirrup pivoted to the bottle acts upon an inclinedsurface on the upper side of the stopper to force and hold the same toits place.

The invention consists in the improved manner ofconstructingthedevice,and particularly in the use of a wire loop servingboth as an inolined surface for the bail to act upon and as a spring toretain the parts in their proper relative positions, as hereinafterexplained; and it consists more particularly in the combination, with atop plate and an elastic stopper below the same, of a vertical plungeror piston and a wire loop which serves to retain the piston in placewith a spring action, and also as the inclined surface for the bail toact upon, as hereinafter more fully explained.

Referring to the accompanying drawings, Figure l is a perspective viewof my device in use, the stopper being closed. Fig. 2 is a vertiealcross-section of the same, the bail being thrown back to release thestopper. Fig. 3 is a view illustratingin vertical section the severalparts or members of the stopper disconnected from each other.

Referring to the drawings, A represents a top plate, having one sidesomewhat elongated and turned upward at a. This plate is also providedwith a central vertical opening, I), and on the under side with anannular flange, c, surrounding said opening, the flange being groovedcireumferentially, as shown.

B represents a plunger or piston, having a tubular neck designed toenter the hole in the plate, and provided at the lower end with ahemispheric head, (I. The upper end of the plunger is provided with atransverse curve or not ch, e, and on one side isbeveledor inclineddownward from said notch, while toward the opposite side it is extendedupward to form an ear,f. Through the upper end of the plunger,transversely of the groove 0, a hole or opening, g, is made to receivethe wire loop, as hereinafter described.

0 represents a rubber or equivalent elastic packing, forming the stopperpropen, This cushion has a peripheral flange upon its upper edge, and isrecessed in the interior to receive the piston B and the flange c of theplate.

Drepresentsthewireloop,formed bydoubling a piece of elastic wire uponitself in the bent or annular form represented and curving the two endsinward.

In assembling the parts the neck of the piston B is inserted through thecentral opening of plate A and the rubber stopper 0 applied over andaround the piston and the flange c in the manner plainly represented inFig. 2. The wire loop D is nextinserted through the opening gin theupper end of the piston above the plate, and the two curved ends of theloop inserted through and secured in the eye a of p the plate, the partsbeing so adjusted that the end of the loop which engages with the pistonis urged upward with a strong spring action. The two ends of the elasticwire forming the loop are formed and closed upon the end ofthe plate A,in practice, in such manner as tot'orm a rigid connection between theloop and the plate, whereby the plate is caused to sustain the loopfirmly in position and render its elasticity available for the purposeof drawing the piston upward. The plate is also preferably madeot'elastie material to co-operate with the loop in throwing the innerend of the latter upward. Itwillbeobserved that whentheparts are thusarranged the piston maybe pushed down ward by the application ofpressure through the plate to extend and expand the elastic stopperbelow the same.

E represents an ordinary bail or stirrup straddling the upper end of thebottle, and having the lower end of its arms pivoted am to a band ofwire encircling the neck of the bottle. The upper horizontal portion ofthe bail is passed, as shown, through the wire loop D, encircling thebail. The bail is swung backward and the stopper l inserted in the mouthof the bottle in the manner represented in Fig. 2, after which the ballis swung upward over the lower inclined side of the loop D until it isseated within and retained by the notch cot the piston. During theswinging movement of the bail through the inclined loop it forces thelatter down ward, causing itin turn to force downward the piston and thestopper upon the latter, the top plate, A, being also at the same timeby the action of the spring forced downward on the top of the stopper.In this way the stopper is pressed or held downward with great firmness,both in the top of the mouth and within the neck. The release of thestopper is eifected by simply swinging the bail backward.

Having thus described my invention, what I claim is 1. Thecombination ofthe plate, the plunger, the elastic stopper, the spring-loop above theplate, and the swinging bail or stirrup.

2. In combination with the plate A, piston B, and elastic stopper (J,theinclined spring-loop D and the bail or equivalent pressure devicearranged to swing within the loop and seat itself in theupper end of thepiston.

3. In a bottle-stopper, the combination of a top plate, a verticalplunger passing through the same, an elastic stopper upon the lower endof a plunger, and pressure devices, substantially as shown, acting uponthe upper end of the piston to force the same downward through theplate.

4. In a stopper, the combination of a perforated plate, a piston passingthrough the same, an elastic stopper applied to the lower end of thepiston, a spring operating to raise the piston, and means, substantiallyas described, to force both the piston and the plate downward.

5. The combination of the plate, the elastic stopper, and the bail withthe plunger having its upper end provided with the seat 0.
